Check domain availability and indicative price

check_domain_availability
Read-onlyIdempotent

Check whether a domain can be registered and get an INDICATIVE retail price. IMPORTANT: this is a read-only lookup — it does NOT buy, register, reserve, or pay for any domain, and it changes nothing. The returned price is GROSS (includes 21% VAT) and indicative only. Set alternatives:true to also check the same name across other common TLDs (be, com, net, eu, nl, io, dev, app). Requires a valid team token but is not tied to a specific site.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
domainYesThe domain to check, e.g. "example.com".
alternativesNoWhen true, also check the same second-level name across a canonical TLD set (be, com, net, eu, nl, io, dev, app) and return each one's availability + indicative price.

Output Schema

A4.7/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, destructiveHint. The description adds critical details: the price is indicative, gross (21% VAT), and the exact list of TLDs for alternatives. No contradictions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is three sentences, front-loaded with purpose, and every sentence provides essential information without redundancy. Perfectly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple two-parameter tool, the description covers purpose, behavioral caveats, parameter usage, and authentication context. It leaves no gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and the description enriches parameters by specifying the exact TLD list for 'alternatives' and providing an example for 'domain'. This adds value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states the verb 'check' and the resource 'domain availability with indicative price', clearly distinguishing it from sibling tools that perform mutations like 'add_custom_domain' or 'deploy_site'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clarifies this is a read-only lookup, does not register domains, and explains when to use the 'alternatives' parameter. It also mentions token requirements. However, it does not explicitly contrast with other tools, but the sibling set makes the distinction clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.2/5.0
Disambiguation5/5

Every tool has a clearly distinct purpose, from deployment and file management to domain configuration and analytics. Even similar-sounding tools like add_files and add_file_chunk are well-differentiated by context and use case.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern using snake_case (e.g., add_custom_domain, list_sites, delete_source_file). The naming is predictable and easy to understand.

Tool Count4/5

39 tools is higher than the typical 3-15 range, but each tool serves a necessary function for a comprehensive deployment platform. The count is justified by the broad feature set, though slightly heavy.

Completeness5/5

The tool set covers the full lifecycle of site deployment, management, backup, custom domains, form handling, analytics, and source editing. There are no obvious gaps for the intended functionality.
